See a stop smoking expert. It's free and will increase your chances of quitting for good. You can talk about which stop smoking aids will work best for you, and they can provide additional support such as advice on managing cravings. They can also talk to you about the two stop smoking medicines available on prescription: Varenicline (Champix) and Bupropion (Zyban)

If you're not as successful as you want to be, you'll still have learnt something to help you next time. The more comfortable you are using the support available, the better prepared you'll be for stopping completely next time.

If you take antipsychotic medicines or antidepressants, it's important you talk to your GP or psychiatrist before you stop smoking – the dosage of these medicines may need to be monitored and the amount you need to take could be reduced.
